Material extrusion (ME) using a filament including metal powders has recently attracted considerable attention because it allows the production of metal parts at low cost. However, like other additive manufacturing processes, metal ME suffers from th

Owing to the deposition mechanism, parts fabricated from the material extrusion (ME) process have intrinsic air gaps that negatively impact their mechanical properties. Thus, the amount of air gaps should be minimized. In this study, a warm isostatic

Selective laser melting (SLM) process based on metallic powders has been broadly adopted for its higher accuracy. In the SLM process, the building of a process window is a fundamental work for fabricating a full-dense part for a new material. Single-
